Obama's grandmother dies in Hawaii

Barack Obama's grandmother has died in Hawaii, his campaign announced. Obama broke off campaigning two weeks ago to visit the ailing Madelyn Dunham, 86.

"It is with great sadness that we announce that our grandmother, Madelyn Dunham, has died peacefully after a battle with cancer," Obama said in a joint statement with his half-sister, Maya Soetoro-Ng.

"She was the cornerstone of our family, and a woman of extraordinary accomplishment, strength, and humility. She was the person who encouraged and allowed us to take chances. She was proud of her grandchildren and great-grandchildren and left this world with the knowledge that her impact on all of us was meaningful and enduring. Our debt to her is beyond measure.

"Our family wants to thank all of those who sent flowers, cards, well-wishes, and prayers during this difficult time. It brought our grandmother and us great comfort. Our grandmother was a private woman, and we will respect her wish for a small private ceremony to be held at a later date. In lieu of flowers, we ask that you make a donation to any worthy organization in search of a cure for cancer."
